- The Thermal Infrared Visual Object Tracking challenge 2016, VOT-TIR2016, aims at comparing short-term single-object visual trackers that work on thermal infrared (TIR) sequences and do not apply pre-learned models of object appearance. VOT-TIR2016 is the second benchmark on short-term tracking in TIR sequences. Results of 24 trackers are presented. For each participating tracker, a short description is provided in the appendix. The VOT-TIR2016 challenge is similar to the 2015 challenge, the main difference is the introduction of new, more difficult sequences into the dataset. Furthermore, VOT-TIR2016 evaluation adopted the improvements regarding overlap calculation in VOT2016. Compared to VOT-TIR2015, a significant general improvement of results has been observed, which partly compensate for the more difficult sequences. The dataset, the evaluation kit, as well as the results are publicly available at the challenge website.

Bokkapitel (refereegranskat)abstract
- This study used generalizability theory to examine the reliability of three transcription measures: handwriting fluency assessed with a copying task and handwriting legibility and spelling assessed with rating scales. A reliable estimate of handwriting fluency at grade one and two can be obtained with a single copying task and rater. Multiple raters and composition tasks in grades one and two are needed to obtain reliable estimates of handwriting legibility and spelling based on rating scales.

Teaching writing during the COVID‑19 pandemic in the 2021–2022 school year
- 2023

Tidskriftsartikel (refereegranskat)abstract
- This study examined if in-class, online, and hybrid (in-class and on-line) instruction provided to middle and high school students in the U.S. differed during the third school year of the COVID-19 pandemic. It also provided a description of how writing was taught to secondary students. Thirty-eight middle and high school teachers (32 female, 6 male), who mostly taught languages arts (84%), were asked to complete a survey each day during the 2020/2021 school year for a single class that best represented how they taught writing. The survey included questions about mode of instruction (in-class at school, online, and hybrid), whether writing or writing instruction was provided that day, and if so, whether 11 specific writing activities occurred. Teachers completed 2676 surveys, and their responses indicated there was only one statistically detectable difference between in-class, online, and hybrid lessons in terms of the proportion of lessons that included each of the targeted writing activities or the time devoted to them. The only difference involved creating digital written products, which occurred more often in hybrid lessons than at school in-class lessons, but not more often in online lessons One significant finding across all reported lessons was that teachers devoted little time to teaching writing. Writing and writing instruction did not occur in close to one-third of all lessons; teachers typically included only one writing activity in a lesson; and an average of just 19 min a lesson was devoted to the targeted writing activities.

A Multicenter Randomized Controlled Trial of Zephyr Endobronchial Valve Treatment in Heterogeneous Emphysema (TRANSFORM)
- 2017
-
Ingår i: American Journal of Respiratory and Critical Care Medicine. - : AMER THORACIC SOC. - 1073-449X .- 1535-4970. ; 196:12, s. 1535-1543

Tidskriftsartikel (refereegranskat)abstract
- Rationale: Single-center randomized controlled trials of the Zephyr endobronchial valve (EBV) treatment have demonstrated benefit in severe heterogeneous emphysema. This is the first multicenter study evaluating this treatment approach. Objectives: To evaluate the efficacy and safety of Zephyr EBVs in patients with heterogeneous emphysema and absence of collateral ventilation.Methods: This was a prospective, multicenter 2:1 randomized controlled trial of EBVs plus standard of care or standard of care alone (SoC). Primary outcome at 3 months post-procedure was the percentage of subjects with FEV1 improvement from baseline of 12% or greater. Changes in FEV1, residual volume, 6-minute-walk distance, St. George's Respiratory Questionnaire score, and modified Medical Research Council score were assessed at 3 and 6 months, and target lobe volume reduction on chest computed tomography at 3 months.Measurements and Main Results: Ninety seven subjects were randomized toEBV(n = 65) or SoC(n = 32). At 3 months, 55.4% of EBV and 6.5% of SoC subjects had an FEV1 improvement of 12% or more (P < 0.001). Improvements were maintained at 6 months: EBV 56.3% versus SoC 3.2% (P < 0.001), with a mean +/- SD change in FEV1 at 6 months of 20.7 +/- 29.6% and -8.6 +/- 13.0%, respectively. A total of 89.8% of EBV subjects had target lobe volume reduction greater than or equal to 350 ml, mean 1.09 +/- 0.62 L (P < 0.001). Between-group differences for changes at 6 months were statistically and clinically significant: Delta EBV-SoC for residual volume, -700 ml; 6-minute-walk distance, +78.7 m; St. George's Respiratory Questionnaire score, -6.5 points; modified Medical Research Council dyspnea score, -0.6 points; and BODE(body mass index, airflow obstruction, dyspnea, and exercise capacity) index, 21.8 points (all P < 0.05). Pneumothorax was the most common adverse event, occurring in 19 of 65 (29.2%) of EBV subjects.Conclusions: EBV treatment in hyperinflated patients with heterogeneous emphysema without collateral ventilation resulted in clinically meaningful benefits in lung function, dyspnea, exercise tolerance, and quality of life, with an acceptable safety profile.

Konferensbidrag (refereegranskat)abstract
- The Visual Object Tracking challenge VOT2016 aims at comparing short-term single-object visual trackers that do not apply pre-learned models of object appearance. Results of 70 trackers are presented, with a large number of trackers being published at major computer vision conferences and journals in the recent years. The number of tested state-of-the-art trackers makes the VOT 2016 the largest and most challenging benchmark on short-term tracking to date. For each participating tracker, a short description is provided in the Appendix. The VOT2016 goes beyond its predecessors by (i) introducing a new semi-automatic ground truth bounding box annotation methodology and (ii) extending the evaluation system with the no-reset experiment.

Tidskriftsartikel (refereegranskat)abstract
- The current study examined the effectiveness of a writing is caught approach with young developing writers in Norway. This method is based on the premise that writing competence is acquired naturally through real use in meaningful contexts. Our longitudinal randomized control trial study tested this proposition by examining if increasing first grade students’ opportunities to write in various genres for different purposes and for a range of audiences over a two-year time period improved the quality of their writing, handwriting fluency, and attitude towards writing. The study included data from 942 students (50.1% girls) in 26 schools randomly assigned to the experimental treatment, and 743 students (50.6% girls) in 25 schools randomly assigned to the business-as-usual (BAU) control condition. Across Grades 1 and 2, experimental teachers were asked to supplement their typical writing instruction by implementing 40 writing activities designed to increase students’ purposeful writing. Increasing experimental students’ writing over the two-year period did not result in statistically detectable differences in the writing quality, handwriting fluency, and attitude towards writing of students in the experimental and BAU control conditions. These findings did not provide support for the effectiveness of the writing is caught approach. Implications for theory, research, and practiced are discussed.

Tidskriftsartikel (refereegranskat)abstract
- The COVID-19 pandemic and the move by governments worldwide to cancel inclass instruction and move to emergency remote instruction in March and April of 2020 created an unprecedented disruption in children’s education. As the COVID-19 pandemic took form and continued to impact education in the following 2020/2021 academic year, multiple concerns were raised about possible negative efects on students’ learning. The current longitudinal replication study examined this proposition for second-grade students in Norway. In a previous investigation (Skar et al. Journal of Educational Psychology 114:1553–1566, 2022), we found that scores for quality of writing, handwriting fuency, and attitude toward writing of frst-grade children tested immediately after emergency remote instruction ended in the Spring of 2020 (During COVID-19 cohort) were lower than the scores of frst-grade students from the same schools tested a year earlier before the start of the pandemic (Before COVID19 cohort). In the present study, we compared the scores for the During COVID-19 cohort (333 girls, 308 boys) on these same writing measures 1 year later at the end of second grade to a During COVID-19 cohort of second-graders (888 girls, 780 boys) from the same schools tested 2 years earlier before the start of the pandemic. The initial negative impact of the COVID-19 pandemic on frst-grade students’ writing observed by Skar et al. (Journal of Educational Psychology 114:1553–1566, 2022) was no longer evident 1 year later at the end of second grade in the current study.

Tidskriftsartikel (refereegranskat)abstract
- This study explored to what extent observable and perceived features of language arts instruction could explain variance in student reading achievement in lower secondary school. Data from classroom observations (using PLATO) and student surveys (using Tripod) were collected to examine the relationships between dimensions of teaching and student achievement gains (N=601). A combination of instructional features that provide coherence and consolidation of new knowledge were found to be positive predictors of reading achievement. The majority of features examined, however, did not significantly explain variance in achievement. We discuss the findings with respect to expected theoretical assumptions and potential measurement limitations.

Tidskriftsartikel (refereegranskat)abstract
- To elucidate the genetic architecture of amyotrophic lateral sclerosis (ALS) and find associated loci, we assembled a custom imputation reference panel from whole-genome-sequenced patients with ALS and matched controls (n = 1,861). Through imputation and mixed-model association analysis in 12,577 cases and 23,475 controls, combined with 2,579 cases and 2,767 controls in an independent replication cohort, we fine-mapped a new risk locus on chromosome 21 and identified C21orf2 as a gene associated with ALS risk. In addition, we identified MOBP and SCFD1 as new associated risk loci. We established evidence of ALS being a complex genetic trait with a polygenic architecture. Furthermore, we estimated the SNP-based heritability at 8.5%, with a distinct and important role for low-frequency variants (frequency 1-10%). This study motivates the interrogation of larger samples with full genome coverage to identify rare causal variants that underpin ALS risk.
